Droid RAZR phone is on and working but screen does not work

Something weird happened with my Droid RAZR yesterday. It was working fine and then next time I went to use it the screen wouldn't light up. It is still receiving calls, e-mails, etc and the indicator lights at the top flash when data comes in and the navigation buttons at the bottom light up as well. But it's a bit useless given that I can't see anything on the screen. Anyone have any experience with this or any ideas on how to make my screen start lighting up again?
